I like the looks of the shorty in the 3.3" barrel and would be curious if a rendition of the super shorty or micro with a 3.1" barrel would be possible.
The original "Shorty" design was 4.92" long. I thought it would be nice to have it under 5", which would make it a true "mouse gun" (that could deliver 475 fpe); however, it got too tight in front to leave enough room for the much-improved unlock block (Gen 8), so the length was increased to 5.1", with a 3.35" barrel. This length was then built in Gen 8 and Gen 9. When you think about it, other guns are 1 to 2.5" longer, which means they have that much room for "dead stop" of the slide. The XR9 design has eliminated that zone, so we are left with a dead stop that comes up very close to the takedown lever (which, by the way, is used as a barrel stop in other brands of firearms). Our takedown lever comes up close to the top cartridge of the magazine, so basically we have made the gun as short possible with the current takedown lever location. If we are able to come up with a different takedown method in the future, we might be able to chop 0.2" off the length of the gun.
Does the current 5.1" OAL include the slight barrel protrusion from the front of the slide?
